This is our very first try at converting a 911R reproduction muffler to 914-6 GT spec. If you wondered why we did this, you'll have to go back a few years when the "new reproduction" 914-6 GT mufflers you see today were NOT available.

The 914-6 GT reproduction mufflers you see today were a by-product of the effort after the 911R muffler was reproduced, it was simply made available years after the 911R and the reason why these photos were taken, we wanted to document what we had to do at that time to make this 914-6 GT mufflers possible. By the way, we used my original 914-6 GT muffler to make this happen. Take a close look.
